Slit Lamp Biomicroscopy
A Detailed, High-Precision Examination of Your Ocular Surface at Réspa
At Réspa – Optometry & Dry Eye Wellness Centre, every dry eye assessment begins with a meticulous slit-lamp examination. This high-magnification microscope allows our Hong Kong–registered optometrists to closely evaluate the front structures of the eyes with exceptional clarity.
Beyond reviewing general ocular health, this essential assessment helps identify subtle factors that may contribute to dry eye–related discomfort, tear film instability, or eyelid dysfunction.
What We Examine
1. Eyelid Margin Health & Blepharitis
Blepharitis is a common contributor to dry eye–related symptoms and is often overlooked. Using the slit lamp, we assess the eyelid margins for:
-
Redness, swelling, or irritation
-
Blockage or debris around the meibomian gland openings
-
Flaking or crusting at the base of the lashes
These findings may affect normal oil secretion from the eyelids, contributing to tear film instability and ocular discomfort.

2. Demodex-Related Eyelid Findings
Demodex mites are microscopic organisms that can reside in the eyelash follicles. When present in higher numbers, they may be associated with eyelid irritation and compromised tear quality. During the examination, we look for:
-
Cylindrical dandruff at the base of the lashes
-
Lash debris or irregular lash growth
-
Signs of eyelid inflammation commonly linked with demodex
Identifying these features allows us to provide targeted eyelid hygiene guidance and supportive in-office eye wellness recommendations.

3. Eyelid Structure & Blink Quality
Healthy eyelid position and blinking are essential for maintaining a stable tear film. The slit-lamp examination allows us to observe:
-
Blink completeness and blink quality
-
Eyelid position or malposition
-
Eyelid laxity or drooping
-
Irregular lid margins that may affect tear distribution
Even subtle variations in eyelid structure or movement can influence tear stability, comfort, and visual clarity.
