Clinical significance of hemorrhages in the optic disc.

A consecutive series of 8029 first visit optometric examinations revealed 20 patients having hemorrhages of the optic disc. Assessment of optic disc contour, intraocular pressure (IOP), and visual fields was undertaken at detection of the hemorrhage and at follow-up not less than 3 months later. The disc hemorrhage patients were assessed for the presence of systemic occlusive disease. The sensitivity of disc hemorrhage as a sign of glaucoma was 0.3 in the sample. There was some risk of visual field loss after detection of a hemorrhage in eyes having glaucoma (1 of 6 eyes); a similar risk was observed in non-glaucomatous eyes in which bleeding occurred (4 of 14 eyes). Hemorrhages occurred in 8 eyes that remained clinically normal during the course of follow-up. Notching of the neural rim of the disc was common but overall changes in contour of the disc were observed in only one patient. An association between disc hemorrhage and systemic disease could not be established.

[Observation of complications at the operative and early postoperative stages of phacoemulsification].

PURPOSE: The study was designed to investigate the reason and management of the complications at the initial stage of studying the technique of phacoemulsification. METHODS: Observing the complications at the operative and early postoperative stages of phacoemulsification used in situ nuclear fracture technique or in iridial plain fracture technique on 233 eyes of 212 patients with cataract. RESULTS: During the operations the rate of vitreous loss was 8.6% (20 eyes); iridial damage was 5.6% (13 eyes); hemorrhage in the anterior chamber was 0.4% (1 eye). After the operations the rate of continued corneal edema was 1.3% (3 eyes); posterior capsular opacity was 3.0% (7 eyes); inflammation was 0.9% (2 eyes); discentral location of intraocular lens was 0.4% (1 eye); leakage of wound was 0.9% (2 eyes); hemorrhage in the anterior chamber was 0.4% (1 eye). CONCLUSION: Vitreous loss and iridial damage were the frequent complications at the initial stage of studying the technique of phacoemusification. The rate of the complications was lower in situ nuclear fracture technique than in iridial plain fracture technique.

Use of 10-Hz flash visual evoked potentials in prediction of final visual acuity in diabetic eyes with vitreous hemorrhage.

In 44 diabetic eyes with vitreous hemorrhage, monocular steady-state visual evoked potentials were elicited through closed eyes by a 10-Hz flash. Visual evoked potentials were rated as normal or abnormal on the basis of amplitude and waveform. Abnormal visual evoked potentials were subdivided into mildly abnormal, markedly abnormal and nonrecordable categories. Patients with normal potentials were predicted to have visual acuities of 6/15 (20/50) or better. Patients with abnormal potentials were predicted to have visual acuities of 6/18 (20/60) or worse. Final visual acuities were the best visual acuities recorded in the 6 months after vitreous surgery (vitrectomy) or spontaneous clearing of the vitreous hemorrhage. The visual evoked potential categories and final acuities were compared with a 2 x 2 contingency table. The accuracy was 86%. The visual evoked potential categories and final acuities were associated at a statistically significant level.

Natural history of retinal pigment epithelial detachments in age-related macular degeneration.

The natural history of 100 eyes of 93 patients with retinal pigment epithelial detachment (PED) and bilateral age-related macular degeneration (AMD) was retrospectively studied for a minimum of 12 months in the offices of Retina Consultants, Ltd. Detachment was defined as serous in 46 eyes, turbid in 12 eyes, hemorrhagic without evident neovascular membrane (NVM) in 20 eyes, and hemorrhagic with angiographically proven NVM in 17 eyes. Final visual results demonstrated visual acuity of 20/200 or worse in 33% of serous PED, 83% of turbid PED, and 89% of hemorrhagic PED. Despite strict inclusion criteria, 26% of serous PED developed NVM by one year and 49% of serous PED developed NVM by three years. Variables associated with NVM development in serous PED include older patient age, larger detachment size, presence of subretinal fluid at initial examination, and disciform scar in the fellow eye at presentation.

[Visual prognosis and macular pathology in eyes with retinal macroaneurysms].

We studied retrospectively the visual outcome of 20 eyes of 19 patients with symptomatic retinal arterial macroaneurysm. The macular pathology responsible for the acute visual loss was categorized as macular edema (5 eyes), preretinal hemorrhages alone (3 eyes), subretinal hemorrhages with or without preretinal hemorrhages (10 eyes) and vitreous hemorrhage (2 eyes). Thirteen eyes were treated with argon or dye laser photocoagulation. Five eyes with preretinal hemorrhage underwent YAG laser photodisruption of the posterior hyaloid membrane to release the preretinal hemorrhage into the vitreous space. Five eyes with macular edema, 3 eyes with preretinal hemorrhage without subretinal hemorrhage and 2 eyes with vitreous hemorrhage showed final vision of 0.5 or better, but of the other 10 eyes with subretinal hemorrhage with or without preretinal hemorrhage, 9 showed final visual acuity of 0.2 or worse. Visual prognosis of submacular hemorrhage due to ruptured retinal macroaneurysm is poor, but that of macular edema, preretinal hemorrhage or vitreous hemorrhage is relatively good.
