A report of a 66-year-old male with keratoconus presenting with an acute hydrops. The patient was managed with intracameral C3F8 gas injection. On postoperative follow-up, slit lamp imaging showed a large central Descemet's membrane tear taking the appearance of a leech, with such well-defined tears in cases of acute hydrops being a rare entity to image on a slit lamp.

A 66-year-old male presented with complaints of gradually progressive blurring of vision in the right eye for 5 years, followed by a sudden drop in vision, redness, watering, pain, and photophobia for 2 days. Visual acuity of the right eye was counting fingers close to face. Slit lamp examination [Figure 1] and anterior segment Optical Coherence Tomography (OCT) revealed features of acute hydrops in the right eye. He underwent intracameral 14% C3F8 gas injection.

Postoperatively (day 5), gas bubble was in situ with a large Descemet's membrane (DM) tear visible on slit lamp examination, the appearance of which simulates a leech. The tear was extending from 2 mm from the limbus at 8'o clock position up to 1'o clock position, passing through the pupillary centre [Figure 2]a and [Figure 2]b. At 6 weeks follow-up, he had stromal scarring [Figure 3] with Anterior Segment Optical Coherence Tomography (AS-OCT) revealing a compact cornea with reabsorption of intrastromal fluid. He underwent penetrating keratoplasty after 3 months.

Hydrops in cases of Keratoconus were characterised by a tear in the DM. The ends of the torn membrane tend to rollaway leading to a gap. This separation paves the way for the aqueous from the anterior chamber to enter into the corneal stroma, thus, leading to oedema.[1],[2] The purpose of intracameral injection of gas is to reduce the duration of corneal oedema. This is achieved by preventing entry of aqueous into the stroma by the gas acting as a tamponade and may also unroll the torn edges of the DM.[1],[3],[4]

Although postoperative DM detachments can be visualised on slit lamp, such well-defined tears following acute hydrops are a rare entity to image on a slit lamp. These images presented here portray a rare presentation of the DM tear in the form of a leech, following intracameral gas injection.
