ABSTRACT: We evaluate the functional and anatomic outcome after intravitreal ranibizumab treatment in patients with choroidal neovascularization (CNV) related to chronic central serous chorioretinopathy (CSC).
This is a small case series of 5 eyes with CNV associated with chronic CSC treated with intravitreal injection of 0.5 mg ranibizumab in the Jules Gonin University Eye Hospital from July 2007 to July 2009. Baseline and monthly follow-up visits included best-corrected visual acuity (BCVA), fundus examination, and optical coherence tomography (OCT). Fluorescein and indocyanine green angiography (ICG) were performed at baseline and repeated at least every 6 months.
We studied 5 eyes of 4 patients with a mean age of 66 years. Mean follow-up was 21 months (SD 1.9). The mean number of intravitreal injections administered for each patient was 10 (SD 4.6). The mean initial BCVA was 0.23 (decimal equivalent) (logMAR 0.64, SD 0.13). At the last follow-up, mean BCVA was 0.44 decimal equivalent (logMAR 0.36, SD 0.31). Mean central macular thickness (CMT) measured with OCT was 330 microm (SD 43) at baseline and decreased at the final follow-up to 243 microm (SD 44 ). Persistent intraretinal or subretinal fluid on OCT and/or multifocal areas of increased choroidal permeability on ICG angiographies were present in all patients at the last follow-up visit.
Intravitreal ranibizumab appeared to be an effective treatment of CNV related to chronic CSC. However, residual intraretinal or subretinal fluid and increased choroidal permeability persisted. Prospective controlled studies are warranted to evaluate the long-term safety and efficacy of intravitreal ranibizumab.

ABSTRACT: To report both the functional and anatomic outcome and safety profile of 23-gauge pars plana vitrectomy combined with membrane peeling and intravitreal injection of triamcinolone acetonide in eyes with idiopathic macular epiretinal membranes.
Retrospective study of 39 consecutive patients who underwent 23-gauge transconjunctival sutureless vitrectomy, membrane peeling, and intravitreal triamcinolone acetonide injection for an idiopathic macular epiretinal membrane between February 2007 and February 2008. Minimum follow-up was 6 months.
Thirty-nine eyes of 39 patients were included in the study. The mean follow-up was 7 +/- 2.2 months (range, 6-15 months). Twenty-two eyes (56%) were pseudophakic and 17 (44%) were phakic at the time of surgery. Five of the phakic eyes (29.4%) had worsening of cataracts during the follow-up period. Mean preoperative intraocular pressure was 14 +/- 3.5 mmHg. At the final follow-up, mean intraocular pressure was 14.5 +/- 2.7 mmHg, which did not differ significantly from the intraocular pressure at baseline (P = 0.14, two-tailed t-test). Five (13%) patients needed topical antiglaucoma treatment. Mean preoperative best-corrected visual acuity (BCVA) was 0.28 decimal equivalent (20/71 Snellen equivalent; logarithm of the minimum angle of resolution 0.54 +/- 0.2, range: 1.0-0.2) and improved significantly (P < 0.0001, two-tailed t-test) to a mean of 0.6 decimal equivalent (20/33 Snellen equivalent; logarithm of the minimum angle of resolution 0.22 +/- 0.16, range: 0.6-0) at the final follow-up. The BCVA improved by a mean of 3.2 +/- 2.1 lines (range: 0-8). Twenty-nine patients (74%) demonstrated a gain of > or =3 lines. Mean central macular thickness was 456 +/- 77 microm (mean +/- SD) at baseline, which was significantly reduced at the final follow-up to 327 +/- 79 microm (mean +/- SD; P < 0.0001, two-tailed t-test). Average central macular thickness reduction was 131 +/- 77 microm (mean +/- SD; range: 36-380 microm). A subgroup analysis of 15 selected cases, which had central macular thickness and BCVA measurements after the first postoperative week, demonstrated that 84% of the total final reduction in central macular thickness and 84% of the total final improvement in BCVA occurred already during the first postoperative week.
Twenty-three-gauge sutureless transconjunctival vitrectomy is a safe and effective technique for the treatment of idiopathic macular epiretinal membranes. The concomitant administration of intravitreal triamcinolone acetonide after pars plana vitrectomy may speed up and improve the anatomic and functional outcome.

ABSTRACT: Retinal pigment epithelium (RPE) tear is an extremely rare complication in patients with classic neovascular membranes without RPE detachment. We evaluate their incidence and functional outcome following treatment with intravitreal ranibizumab.
Observational study of 72 consecutive patients (74 eyes) treated at Jules Gonin University Eye Hospital, Lausanne, with intravitreal ranibizumab 0.5 mg for classic choroidal neovascularization (CNV) between March 2006 and February 2008. Best-corrected visual acuity (BCVA), fundus examination and optical coherence tomography were recorded monthly; fluorescein angiography was performed at baseline and repeated at least every 3 months.
RPE tears occurred in four (5.4%) eyes temporal to the fovea, after a mean of four injections (range 3-6). Mean baseline BCVA was 0.25 decimal equivalent (logMAR 0.67) and improved despite the RPE tear to 0.6 decimal equivalent (logMAR 0.22).
RPE tears following intravitreal ranibizumab injections for classic CNV can occur in about 5% of patients, even in the absence of baseline RPE detachment. Nevertheless, vision may improve provided the fovea is not involved.

ABSTRACT: Retinal angiomatous proliferation (RAP) is a distinct variant of neovascular age-related macular degeneration (AMD). The aim of this study is to evaluate the functional and anatomic outcome after intravitreal ranibizumab (Lucentis) treatment in patients with RAP.
Prospective study of consecutive patients with newly diagnosed or recurrent RAP treated with intravitreal ranibizumab at the Jules Gonin Eye Hospital between March 2006 and December 2007. Baseline and monthly follow-up visits included best-corrected visual acuity (BCVA), fundus exam and optical coherence tomography. Fluorescein and indocyanine green angiography were performed at baseline and repeated at least every 3 months.
Thirty-one eyes of 31 patients were treated with 0.5 mg of intravitreal ranibizumab for RAP between March 2006 and December 2007. The mean age of the patients was 82.6 years (SD:4.9). The mean number of intravitreal injections administered for each patient was 5 (SD: 2.4, range 3 to 12). The mean follow up was 13.4 months (SD: 3, range 10 to 22). The baseline mean logMAR BCVA was 0.72 (SD: 0.45) (decimal equivalent of 0.2). The mean logMAR BCVA was improved significantly (P < 0.0001) at the last follow-up to 0.45, SD: 0.3 (decimal equivalent 0.35). The visual acuity (VA) improved by a mean of 2.7 lines (SD 2.5). Mean baseline central macular thickness (CMT) was 376 microm, and decreased significantly to a mean of 224 microm (P < 0.001) at the last follow-up. Mean reduction of CMT was 152 microm (SD: 58). An average of 81.5% of the total visual improvement and 85% of the total CMT reduction occurred during the first post-operative month after one intravitreal injection of ranibizumab. During follow-up, an RPE tear occurred in one eye (3.2%) of the study group. No injection complications or systemic drug-related side-effects were noted during the follow-up period.
Intravitreal ranibizumab injections appeared to be an effective and safe treatment for RAP, resulting in visual gain and reduction in macular thickness. Further long-term studies to evaluate the efficacy of intravitreal ranibizumab in RAP are warranted.

ABSTRACT: To evaluate the histologic features of cellular retinal fragments on the internal limiting membrane (ILM) removed during idiopathic macular epiretinal membrane (MEM) peeling surgery with and without the aid of indocyanine green (ICG) diluted in 5% glucose.
ILM specimens removed from 88 eyes during idiopathic MEM surgery between 1995 and 2003 were reviewed retrospectively. Histologic analysis focused on the presence and characteristics of retinal fragments on the retinal surface of the ILM. Statistical analysis compared the results between group I (conventional surgery) and group II (ICG-assisted peeling).
Seventy-one eyes underwent MEM surgery without the aid of ICG (group I) and seventeen underwent MEM ICG-assisted surgery (group II). The amount of Müller cell debris on the retinal surface of the ILM was more significant in the group I than in the group II (40.8 vs. 11.8; P = 0.024). Large fragments of Müller cells were more frequently observed in the group I (no ICG) than in the group II (ICG) (63.4 vs. 23.5%; P = 0.003).
The use of ICG diluted with 5% glucose in ILM removal during MEM surgery was associated with less retinal debris attached to the retinal face of the ILM compared with surgery in which ICG was not used.

ABSTRACT: Macular choroidal neovascularization (CNV) is one of the most vision-threatening complications of myopia, which can lead to severe vision loss. The purpose of this study was to evaluate the safety and efficacy of intravitreal ranibizumab in the treatment of myopic CNV.
We conducted a prospective, consecutive, interventional study of patients with subfoveal or juxtafoveal CNV secondary to pathologic myopia (PM) treated with intravitreal injection of ranibizumab in the Jules Gonin University Eye Hospital from June 2006 to February 2008. Best-corrected visual acuity (BCVA), optical coherence tomography (OCT), and fluorescein angiography (FA) were performed at baseline and monthly for all patients. Indications for retreatment were loss in BCVA associated either with persistent leakage from CNV shown on FA, and/or evidence of CNV activity on OCT.
The study included 14 eyes of 14 patients. The mean spherical equivalent refractive error was -12.5 (range, -8.0 D to -16.0 D). Mean time of follow-up was 8.4 months (range from 3 to 16 months, SD: 3). The mean number of intravitreal injections administered for each patient was 2.36 (SD 1.5). The mean initial visual acuity (VA) was 0.19 decimal equivalent (log-MAR: 0.71, SD: 0.3). A statistically significant improvement to a mean VA of 0.48 decimal equivalent (log-MAR:0.32, SD: 0.25) was demonstrated at the final follow-up. VA improved by a mean of 3.86 (SD 2.74) lines. Nine patients (64%) demonstrated a gain of 3 or more lines. Mean central macular thickness (CMT) measured with OCT was 304 microm (SD: 39) at the baseline, and was reduced significantly at the final follow-up to 153 microm (SD: 23). Average CMT reduction was 170 microm (SD: 57). No injection complications or drug-related side effects were noted during the follow-up period.
In this small series of eyes with limited follow-up, intravitreal ranibizumab was a safe and effective treatment for CNV secondary to PM, resulting in functional and anatomic improvements.
