ABSTRACT: To analyse quantitatively the anterior segment configuration in eyes with nanophthalmos before and after cataract surgery.
This was a retrospective, non-comparative, interventional case series. Eleven eyes in eight patients with nanophthalmos who underwent phacoemulsification and intraocular lens implantation were identified from the department's surgical log, and their clinical records were retrospectively reviewed. Main outcome measures were as follows: visual acuity, intraocular pressure (IOP), axial length and the following ultrasound biomicroscopy parameters: angle opening distance at 500 μm anterior to the scleral spur (AOD500), trabecular-iris angle (TIA) and trabecular ciliary process distance.
The mean axial length of the eyes was 17.3 ± 1.7 mm. AOD500 and TIA increased after cataract surgery (p<0.005). Smaller axial length, AOD500 and TIA before cataract surgery were observed in eyes with preoperative IOP elevation than those without preoperative IOP elevation (p<0.05). Lower postoperative IOP was correlated with greater AOD500 and TIA before cataract surgery (p<0.05).
Cataract surgery deepened the anterior chamber and widened the anterior chamber angle in nanophthalmic eyes. Cataract surgery may have beneficial effects on IOP in eyes with nanophthalmos.

ABSTRACT: We report a patient with acute angle-closure glaucoma secondary to annular ciliochoroidal detachment after unsutured cataract surgery.
An 82-year-old man was diagnosed with bilateral shallow central anterior chamber depth, flat peripheral anterior chamber, and elevated intraocular pressure. One day previously he had undergone uncomplicated unsutured cataract surgery in the right eye and eight days previously, in the left eye. Ultrasound biomicroscopy revealed annular ciliochoroidal detachment in both eyes. Treatment with intravenous methyl prednisolone deepened the anterior chamber and reduced intraocular pressure.
Annular ciliochoroidal detachment may lead to anterior rotation of the ciliary body and angle-closure. This clinical entity is indistinguishable from malignant glaucoma when the fundus cannot be visualized.

ABSTRACT: To report a case of severe hypotony after macular translocation with 360-degree retinotomy.
Interventional case report.
A 50-year-old woman with myopic neovascular maculopathy underwent macular translocation with 360-degree retinotomy in her left eye.
After the second procedure of silicone oil removal, severe hypotony developed. No clear sign of leakage was found. Pure perfluoropropane gas tamponade was then performed, which resulted in temporal resolution of severe hypotony, but the hypotony recurred as the gas bubble was absorbed. Ten weeks after the second surgery, the hypotonous eye was refilled with silicone oil. No apparent cyclitic membrane was observed intraoperatively. After this procedure, the choroidal and retinal folds regressed; intraocular pressure has been between 5 and 7 mm Hg for more than 4 months thereafter.
Severe hypotony can occur as a complication of otherwise uneventful macular translocation with 360-degree retinotomy.

ABSTRACT: Ultrasound biomicroscopy(UBM) was performed on filtering blebs with laser treatment including laser gonioplasty(GP), laser iridotomy(LI), and YAG laser trabeculopuncture(YLT) after non-penetrating trabeculectomy(NPT). The filtering blebs were grouped into four types, L, H, E and F, and the spaces under the scleral flap were classified into three. La, S, and N.
In case 1, an F type, an S bleb was not changed despite laser treatment 9 months after NPT. In case 2, YLT was performed twice to release the incarcerated iris. The filtering bleb was changed to the L type, an La bleb. In case 3, an F type, an S bleb was turned into an H type after GP, LI, and YLT. In case 4, GP effectively released peripheral anterior synechia formation and the filtering bleb was kept as an L type, La.
Appropriate laser treatment may be effective in turning a flattened and localized bleb into a good filtering bleb.
