ABSTRACT
BACKGROUND: The most common complication after vitrectomy is the rebleeding in vitreous cavity. It is important to detect the different factors that can increase the vitreous rebleeding rate in these patients. OBJECTIVE: To carry out a retrospective review of the rate of vitreous rebleeding after vitrectomy or phacovitrectomy. METHOD: Retrospective, descriptive and comparative study of patients with a diagnosis of proliferative diabetic retinopathy with phacovitrectomy or vitrectomy procedure. Personal background data, type of surgical intervention and grade of the surgeon who carried out the procedure were obtained. RESULTS: 1227 files of diabetic patients with vitrectomy or phacovitrectomy were reviewed. 65% presented systemic arterial hypertension. The average glomerular filtration rate was 63.50 (±32.36)â¯ml/min/1.73â¯m2 and glycosylated hemoglobin (HBA1C) of 8% (4.6 to 15%). In the comparison of variables, a significant difference in the rate of vitreous rebleeding was obtained comparing phacovitrectomy with vitrectomy. (pâ¯=â¯0.003), in the relationship between vitrectomy with vitreous rebleeding, an odds ratio of 1.44 was obtained. CONCLUSION: The results obtained show a lower rate of rebleeding in patients undergoing phacovitrectomy in patients with proliferative diabetic retinopathy.

A series is presented of sixteen cases of retinal capillary haemangioma (RCH) from consecutive patients at an ophthalmology teaching hospital in Mexico City. There were seven primary haemangioblastomas, and nine due to von Hippel-Lindau disease (VHL). All cases associated with VHL already had systemic manifestations, such as, cerebellar, medullary and renal tumours. Treatment of capillary haemangiomas must be individualised, based on several factors, including the number of lesions, exudation, or presence of retinal detachment. A multidisciplinary approach is essential.

Se presenta una serie de 16 casos de hemangioma capilar retiniano de pacientes valorados en un hospital oftalmológico de enseñanza en la Ciudad de México: 7 de ellos eran hemangioblastomas primarios y 9 eran secundarios a enfermedad de von Hippel-Lindau. Todos los casos relacionados con esta enfermedad presentaban en ese momento manifestaciones sistémicas como: tumores cerebelosos, medulares o renales. El tratamiento para el hemangioma capilar retiniano debe ser individualizado con base en diversos factores como el número de lesiones, la exudación o la presencia de desprendimiento de retina asociado. Se debe de contar con un abordaje multidisciplinario (AU)

Differential diagnosis between a melanoma and a pseudomelanoma requires many years of experience and ocular studies, and requires paying attention to the smallest details. The case is presented of a 57 year-old male with an adenoma of the ciliary body pigment epithelium that was treated with an enucleation of the eye due to a suspicion of a choroidal melanoma.
