Vitreous hemorrhage acounted for 64 patients(67 eyes) seen during a eighteenmonth period from March 1, 1987, to August 31, 1988. In order of decreasing frequency, the major causes were diabetic retinopathy(19.4%), trauma(l1.9%), silent retinal tear(10.4%). retinal branch vein occlusion(7.5%), acute posterior vitreous detachment(7.5%), Eales' disease(6%), Hypertension(6%), central retinal vein occlusion(4.4%). And the minor causes were rhegmatogenous retinal detachment(3%), retinal angioma(3%), chronic renal failure(3%), subretinal neovascularization(1.5%), disc neovascularization with undetermined cause(1.5%). No cause could be determined in 14.9% of the cases.

PURPOSE: To investigate postoperative visual acuities of patients who underwent vitrectomy for their dense nondiabetic vitreous hemorrhage, and in addition to assess postoperative visual results of the group who underwent early vitrectomy. METHODS: Included in the study were 52 patients (52 eyes) who had undergone vitrectomy and been followed up for longer than 4 months after surgeries. Authors investigated the underlying diseases of vitreous hemorrhage, surgical outcomes, and the rate of complications. In addition, we evaluated the results of the group who had undergone vitrectomy between 4 weeks and 6 weeks after development of hemorrhage. RESULTS: The most common cause of vitreous hemorrhage was branch retinal vein occlusion followed by macular hole, ocular trauma, central retinal vein occlusion, age related macular degeneration, Terson`s syndrome, and unknown cases. Visual acuity before operation is less than light perception to 0.3 and improved in 44 eyes (84.6%) after operation. The rate of more than 5 lines' improvement is 63.4% (33 eyes) and 51.9% (27 eyes) obtained their visual acuity of 0.5 or better. In the group which had been operated 4 to 6 weeks after the development, visual acuity improved in 100% (16 eyes). Thirteen eyes (81.2%) showed more than 5 lines' improvement of their visual acuity and 12 eyes had 0.5 or better (75.5%). The most common complication after surgeries is cataract in 5 eyes (10.8%), others were macular hole in 3 eyes (5.7%), retinal detachment in 2 eyes (3.8%), macular hole in 1 eye (6.2%). CONCLUSIONS: Pars plana vitrectomy is a good procedure to improve visual acuity for the patients who have suffered persistent visual disturbances due to non-diabetic vitreous hemorrhage. Also, early vitrectomy should be considered for early visual rehabilitation.

Forty three eyes with vitreous hemorrhage caused by branch retinal vein occlusion had been underwent pars plana vitrectomy and followed-up over 6 months. The eyes were classified into 4 groups according to intraoperative fundus findings-group 1; vitreous hemorrhage only, group 2; vitreous hemorrhage with fibrovascular proliferation, group 3; vitreous hemorrhage with traction retinal detachments, group 4; vitreous hemorrhage with rhegmatogenous retinal detachments. Analysis was focused on the clinical characteristics and postoperative outcome in each group. The durations of vitreous hemorrhage were longer significantly in group 2 and group 3. The vision improved postoperatively in 35 of 43 eyes(81.3%). The percentage of postoperative visual improvements was 100%(18 of 18 eyes) in group 1, 85.7%(12 of 14 eyes) in group 2, 66.6%(4 of 6 eyes) in group 3, and 20$(1 of 5 eyes) in group 4. The preoperative ultrasono-graphic findings of retinal status were accorded with intraoperative retinal findings in 74.4% of eyes.

Vitreous fluorophotometry was used to measure blood retinal barrier permeability to fluorescein in 15 patients with branch retinal vein occlusion(BRVO). Mean posterior vitreous fluorescein concentration(3mm) was 20.0 +/- 11.3(ng/ml) in affected eyes, and 2.99 +/- 1.22(ng/ml) in unaffected eyes. There was a statistically significant difference between the affected eye and unaffected eye(p<0.05). Also there was a correlation between the hemorrhage area and the posterior vitreous fluorescein concentration(r2=0.819). This study revealed that the permeability of blood retinal barrier was increased in BRVO as compared to the contralateral eye, and the higher permeability values were associated with the extent of area involved.

This is a descriptive study of Tersons syndrome among patients with aneurysmal subarachnoid hemorrhage at the Philippine General Hospital. The incidence of Tersons syndrome was 13.4 percent. There were no statistically significant differences in outcomes among patients with and without Tersons syndrome. (Author)

Eales disease is an uncommon idiopathic vasoproliferative retinal disease that primarily affects the peripheral retina. We experienced a 17-year-old male patient who was referred to our clinic because of retinal hemorrhage at the superior temporal quadrant of his left eye. After excluding other causes of branch retinal vein occlusion with medical evaluation, the primary branch retinal vein occlusion was diagnosed. During the follow-up period, retinal vasculitis developed in the peripheral retina of his both eyes along with rapid development of the neovascularization in the left eye. Eales disease was diagnosed. In spite of scattered laser photocoagulation, vitreous hemorrhage eventually occurred, requiring pars plana vitrectomy. We emphasize the occurrence of the branch retinal vein occlusion in young patient with Eales disease.

The authors report 2 patients presenting with visual disturbance due to retinal hemorrhage which developed 1 week after clipping of aneurysm in subarachnoid hemorrhage. Funduscopic findings and pathogenesis of retinal hemorrhage are presented & reviewed. Fortunately funduscopic examination seems to be mandatory for early detection of delayed retinal hemorrhage in subarachnoid hemorrhage.

PURPOSE: To report a patient with multiple subretinal and intraretinal hemorrhages in the absence of retinal/choroidal lesions, diagnosed with infective endocarditis (IE). CASE SUMMARY: We describe the case of a 44-year-old male with an acute decrease of vision in his right eye. Ophthalmic evaluation revealed multiple subretinal and intraretinal hemorrhages, but no choroidal or other retinal lesions. A systemic examination revealed a pansystolic murmur and blood cultures with echocardiography were suggestive of IE. CONCLUSIONS: Thorough systemic evaluations are important when patients present with subretinal and intraretinal hemorrhages in the absence of other retinal/choroidal lesions.

In the literature, Terson's syndrome most commonly co-occurs with subarachnoid hemorrhage(SAH) secondary to rupture of an A-com or ICA aneurysm. It is usually observed bilaterally and the prognosis is poor. The authors report two rare cases of unilateral Terson's syndrome after rupture of MCA bifurcation aneurysm rupture. In both cases, retinal hemorrhage was noticed after early aneurysmal clipping ; after these were conservatively treated, the visual acuity of one patient improved slightly and that of the other showed no change. For early detection and proper management of retinal hemorrhage after subarachnoid hemorrhage, early and periodic fundoscopic examination appears to be important.
