  Abstract 


Asymptomatic free floating vitreous cyst with macular coloboma constantly been stable for 10 years is a rarely reported case. Here, we report a case of 30-year-old male who presented to us with best corrected visual acuity of 6/12 and 6/18 in right and left eye, respectively. On slit-lamp examination anterior segment was normal. His fundus examination showed a solitary free floating cyst in the vitreous in right eye and bilateral macular coloboma. Blood tests for toxoplasmosis and cysticercosis were negative. The patient had no symptoms, so we decided to follow the patient without any treatment.

  Case Report Top


Vitreous cysts either congenital or acquired are rarely observed and symptomatic, so they are regarded as ocular curiosities.[1],[2] We report an unusual case of asymptomatic free floating vitreous cyst with regular follow-up for the past 10 years.

The patient had come to our hospital 10 years back looking for any betterment in his vision as he had diminished vision from childhood. He had no ocular trauma or infection. His best corrected visual acuity was 6/12 and 6/18 in right and left eye, respectively in 2009. Anterior segment was normal. Fundus examination showed retino-choroidal coloboma at the macula in both the eyes and a free floating round translucent cyst [Figure 1] in mid-vitreous measuring 4-5 DD with few pigments on it in right eye. Macular optical coherence tomography also confirmed it [Figure 2]. An ultrasound B-scan revealed a well-defined round 5.8 × 5.5 mm cyst with no hyperdense center [Figure 3]. Blood serology were negative for parasites. Computed tomography brain and orbit were normal. Since the patient did not complain of any visual disturbances related to cyst, we decided to observe the vitreous cyst with regular follow-up. Patient has been regularly followed for the past 10 years. And we noticed that the patient has been asymptomatic all throughout the follow-up periods and vision seemed to be stable 6/12 (right eye) and 6/18 (left eye) and the vitreous cyst also was of the same size [Figure 4].

  Discussion Top


Argon laser photocystotomy, Nd YAG photocystotomy and surgical aspiration are the methods for cyst removal.[3],[4] In the presented case, the patient was asymptomatic, so we decided to observe the cyst. From this report, we would like to highlight that not all vitreous cysts require intervention. This is one of the kinds of unusual report of vitreous cyst observed over a period of 10 years.


  Conclusion Top


We report a rare case of macular coloboma with an asymptomatic free-floating vitreous cyst.
