Brief Summary:

Purpose: To describe an extensive scleral excision technique to treat or prevent uveal effusion in nanophthalmic eyes.

Design: Prospective interventional case series.


  • Setting: Institutional.
  • Patient Population: Consecutive patients with nanophthalmos were operated on by one surgeon.
  • Intervention Procedure: A single, 90% thickness scleral window extending from immediately behind the extraocular muscle insertions to the vortex veins was performed for 3 and 1/4 quadrants as a circumferential strip.
  • Main Outcome Measure: Resolution or prevention of uveal effusion.

Condition or disease Intervention/treatment Phase
Nanophthalmos Procedure: sclerectomy Not Applicable

Detailed Description:
Surgical Technique All surgeries were performed under general anesthesia by one surgeon (AMM). Because the majority of the patients were young with narrow palpebral fissures and very deep set globes in small orbits, special surgical techniques were required. Lateral canthotomy was performed on all patients except for the first. Limbal 360o conjunctival peritomy was followed by securing of each rectus muscles with a modified muscle hook and 2-0 silk suture. Scleral dissection was performed from immediately behind to the muscle insertions posterior to the vortex veins. A 90% depth scleral window was excised over 3 and ¼ quadrants, excluding 3/4 of the superior temporal quadrant to avoid damaging the superior oblique muscle.
