Looking for the ophthalmology diagnostic procedures textbook now.

The library has two ophthalmology books but neither is specifically titled "Diagnostic Procedures in Ophthalmology." Let me search both for B-scan content around pages 242-257.

The Wills Eye Manual has a B-scan section with images. Let me read that block to find all B-scan images, and also check the Kanski block that has B-scan content.

I can see B-scan images in the Wills Eye Manual block3. The page markers show page 1091-1092 area. The user wants pages 242-257 specifically. Let me check what pages those correspond to in the Wills Eye Manual and also search for a "Diagnostic Procedures in Ophthalmology" book specifically. Let me also read more of the Wills Eye Manual B-scan section to get all images.

The library does not have a book specifically titled "Diagnostic Procedures in Ophthalmology." That is a separate textbook (commonly by HV Nema or similar authors) which is not in this collection. However, I can see the Wills Eye Manual has a dedicated B-scan ultrasonography section. Let me check what page numbers the Wills Eye Manual content on pages 242-257 would correspond to, and also look for any page markers around those numbers in the ophthalmology books.

The library does not contain "Diagnostic Procedures in Ophthalmology" (the Nema textbook). However, let me check what's in the Wills Eye Manual around pages 242-257 and also look for B-scan images across the ophthalmology books in the library.

Let me search for page markers in the format used in these books for pages 242-257 in the Wills Eye Manual.

The library doesn't have "Diagnostic Procedures in Ophthalmology" (the dedicated textbook, commonly authored by HV Nema). The two ophthalmology books available are Kanski's and Wills Eye Manual - neither has pages 242-257 as a B-scan section (Wills has B-scan at pages ~1091-1095).

Let me now fetch all the B-scan images that ARE available in the library from the dedicated B-scan ultrasonography section in Wills Eye Manual, and also read more of that section to get all the B-scan figures. I'll also read the next portion of the Wills block to catch all images.

Now I have a clear picture. Let me fetch all the B-scan images from the Wills Eye Manual's ultrasonography section and from Kanski's. I'll fetch all the image URLs I've found.

I have the B-scan images from the available ophthalmology textbooks. Now let me also fetch the remaining B-scan images from Kanski's (the retinal detachment B-scan and the cross-section diagram).

I now have all the available B-scan images from the library. Let me present a clear response to the user.

Important note: The specific textbook you're asking about - "Diagnostic Procedures in Ophthalmology" (commonly by HV Nema / Nitin Nema) - is not available in this library's collection. The library only has two ophthalmology textbooks:

Neither of these has pages 242-257 covering a dedicated B-scan chapter.

That said, here are all the B-scan ultrasound images available from the ophthalmology textbooks in this library:

FIGURE 14.8.2 - Normal B-scan ultrasonography (p. 1093)

To get pages 242-257 specifically from "Diagnostic Procedures in Ophthalmology" (Nema), that textbook is not in this library's collection. If you have a physical copy or PDF, I can help you work through its content. Alternatively, if you're looking for a particular pathology's B-scan appearance (e.g., retinal detachment, choroidal melanoma, vitreous hemorrhage, optic disc drusen), I can pull those specific B-scan images from Kanski's or Wills Eye Manual.

Searching all B-scan pathology images across both ophthalmology textbooks simultaneously.

Good hits. Now let me read around the specific line ranges that contain B-scan images for each pathology - melanoma (Kanski block6 ~865), RD (Wills block2 ~8248, Kanski block5 ~354, Kanski block6 ~1335), and also search for choroidal detachment, vitreous hemorrhage, and other conditions.

Excellent. I now have image URLs for: choroidal melanoma B-scans (Kanski block6 ~865-875), tractional RD B-scan (Kanski block5 ~363), RD B-scan (Wills block2 ~8265), and need to read posterior scleritis (Kanski block2 ~6058), vitreous haemorrhage (Kanski block5 ~779), retinoblastoma calcification (Kanski block6 ~1335). Let me fetch all the confirmed B-scan image URLs and read the remaining blocks.

Excellent - I have multiple confirmed B-scan image URLs. Now let me fetch the remaining ones: posterior scleritis T-sign, vitreous haemorrhage B-scan (block5 ~17.1C/D), retinoblastoma calcification B-scan, choroidal melanoma dome + collar stud B-scans, and also look for vitreous haemorrhage images and asteroid hyalosis images.

I have confirmed all the B-scan image URLs. Let me now fetch the remaining ones: the choroidal melanoma dome B-scan (f2a796), the collar-stud B-scan (already fetched as 21aad4), vitreous haemorrhage B-scans, and the longstanding RD cyst B-scan. Let me get the vitreous haemorrhage images from block5 and the melanoma dome image.

I have all the key B-scan images. Let me get the PVD B-scan and the vitreous haemorrhage B-scan images from Kanski block4 and block5.

I now have all the vitreous haemorrhage B-scan image URLs (ef8671 = VH with flat retina, and one showing RD). Let me fetch these final B-scan images.

I now have a comprehensive collection of B-scan images across all major pathologies. Here is the complete organized gallery:

Rhegmatogenous Retinal Detachment - B-scan (Wills Eye Manual, Fig. 11.3.3, p. 765)

Tractional Retinal Detachment - B-scan (Kanski's, Fig. 16.34B, p. 706)
