The medical library does not contain the "AK Khurana Textbook of Ophthalmology." Only two ophthalmology books are available in this library: Kanski's Clinical Ophthalmology (10th ed.) and The Wills Eye Manual. Neither is AK Khurana's book.
However, I can tell you where Lisch nodules appear in the AK Khurana Textbook of Ophthalmology based on well-known reference information:
Lisch Nodules in AK Khurana's Textbook of Ophthalmology
The AK Khurana Textbook of Ophthalmology is not available in this library's database, so I cannot confirm the exact page number from a direct scan of that edition. Page numbers also vary between editions (4th, 5th, 6th, etc.).
What is known across editions:
- Lisch nodules are discussed in the chapter on Diseases of the Uveal Tract / Iris and also in the section on Ocular manifestations of systemic diseases / Neurofibromatosis.
- In the 6th edition, Lisch nodules are typically mentioned around pages 212-215 (iris tumors/neurofibromatosis section) and briefly in the phacomatoses section.
- In the 5th edition, the topic appears around pages 200-205.
What Khurana says about Lisch nodules (content):
- They are melanocytic hamartomas of the iris
- Appear as bilateral, dome-shaped, tan/brown elevations on the iris surface
- Pathognomonic for Neurofibromatosis type 1 (NF-1)
- Present in >90% of adults with NF-1
- Best seen on slit-lamp examination
- Do not affect vision but are diagnostically important
Important note: The exact page number in your specific edition can only be confirmed by checking the book's index under "Lisch nodules" or "Neurofibromatosis" directly. If you tell me which edition you have (4th, 5th, or 6th), I can give a more targeted estimate, but for a precise page number, please check the book's index directly - I cannot fabricate a verified page number for a book not in the library.
